The AN/PVS-7 is a biocular housing that was originally produced by Litton Industries for the U.S. military.

It has been replaced by the AN/PVS-14, but is still being produced by Elbit Systems Of America.

It uses a single MX-10130 format image intensifier tube.

Collimator

  • A black tube with a prism at one end

    A AN/PVS-7 collimator assembly, comprised of multiple lenses and a triangular prism to duplicate the output image from one MX-10130 tube into both oculars

  • A series of different convex lenses followed and metal rings

    When disassembling, lenses and metal rings come out in the indicated order (left first, right last)

  • Step 1: Insert the lens with the convex side facing towards the collimator housing

    Step 1: Insert the lens with the convex side facing towards the collimator housing

  • Step 2: Insert one of the thick metal rings

    Step 2: Insert one of the thick metal rings

  • Step 3: Insert the thick lens, convex side facing towards the collimator housing

    Step 3: Insert the thick lens, convex side facing towards the collimator housing

  • Step 4.1: Three components needed to be placed together in a bundle

  • Step 4.2: Place the metal ring onto a flat surface for convenience

    Step 4.2: Place the metal ring onto a flat surface for convenience

  • Step 4.3: Place the lens onto the metal ring with the convex side facing towards it

    Step 4.3: Place the lens onto the metal ring with the convex side facing towards it

  • Step 4.4: Place the thin metal ring onto the lens

    Step 4.4: Place the thin metal ring onto the lens

  • Step 4.5: The final result should look like this with each component stacked according to their collerated numbers from 4.1

    Step 4.5: The final result should look like this with each component stacked according to their collerated numbers from 4.1

  • Step 5: Insert the fully stacked components from step 4 with the thin metal ring facing towards the collimator housing

    Step 5: Insert the fully stacked components from step 4 with the thin metal ring facing towards the collimator housing

  • Step 6: Insert the final lens into the collimator housing with the convex side facing outward

    Step 6: Insert the final lens into the collimator housing with the convex side facing outward

  • Step 7: Screw in the lock ring to securely all the components in place

    Step 7: Screw in the lock ring to securely all the components in place
